Application of polyacrylamide in iron ore wastewater

The principle of polyacrylamide is used for iron ore wastewater treatment. In the iron ore beneficiation process, the raw ore is first crushed to a reasonable fineness and then sent to the ball mill by the elevator and the ore feeder to crush and grind the ore. The treatment of iron ore wastewater requires polyacrylamide flocculant.
